<h2>equation</h2>



<pre>

 \begin{equation}

  math formula

 \label{eqno1}

 \end{equation}

</pre>


<p>The equation environment centers your equation on the page

    and places the equation number in the right margin.</p>


<p>The <tt><a href="ltx-252.html">\label</a></tt> command is

    required only if you want to use a

    <tt><a href="ltx-303.html">\ref</a></tt> command to refer to the

    number assigned to this equation. </p>


<p>The <a href="ltx-421.html">Display Math</a> environment gives

    the same effect without the equation number.</p>
